Your M2 MacBook Pro really struggles? That is genuinely crazy, given that I use one as a daily driver and it feels just as fast as the day I bought it.
I think the Apple Silicon transition has increased Mac longevity far beyond the Intel or PowerPC eras, and I am quite baffled you think otherwise.
You’re right, it’s 6 year old, so a dinosaur by technology standards! I see your point.
Is it an Intel MacBook? I think those sucked for obvious reasons outside Apple’s control (Intel getting stuck at 14nm for ages) which they’ve already fixed (by abandoning Intel).
The M1 MacBook Air was more powerful than the top Intel i9 MBP config if I recall correctly.
